Should the Omegapak 8804 PT capactiors be replaced if the unit has been sitting for a while?

Whether the capacitors need to be replaced may depend on how long the unit has been sitting.

Also, while they may not need to be replaced, it may be necessary to perform a re-forming procedure to ensure their proper operation.  

Over time, electrolytic caps loose biasing and chemical structure.  This results in possible short term loss of capacitance and may short out if full voltage is applied. This may require forming, by slowly charging them up (usually with a high pot) to rated voltage.
